Its where one has to be careful as a convert - best to suffer through the boredom than open one's mouth. I had a friend who was cradle Antiochian who told me one night that she felt *intimidated* by the converts: they were all running around knowing Scripture, having read all these Church Fathers and Orthodox theologians, liturgy geeks who attended services that most in her family rarely went to. Her concerns were echoed by a few other members of her parish who thought converts were 'scary'. A little bit of stress was also over cultural items the cradle Orthodox had picked up here in America from Protestant churches (Sunday school, wearing double-breasted suits, Contemporary Christian Music, Parish council wars, Protestant anti-Catholic polemics, Televangelists/Marian apparitions/Vassula Ryden, etc.) that the new converts knew were not part of the Orthodox faith, and often rejected as baggage from Protestantism. After all, every adult convert has a specific list as well as all encompassing statements of rejection of error they must make - as well as statements about what they submit to in Orthodoxy (it wouldn't hurt for those baptized as children were aware of what all is included and rejected in those services - I'm making sure my little cradle Orthodox children do.)
So, their Orthodoxy might not be the Orthodoxy that their ancestors had in the Old World, but they wouldn't know it - what they have in their American parishes is all they've known (as well as what they've picked up from attending Episcopal, Methodist, Catholic/Maronite, Presbyterian, Baptist churches.) That's besides all the stuff about converts who try to coopt the heritage of their new parish, and get neck-deep into ethnic folklore, politics, or much else that the folk raised in that culture are likely not to care about or even be aware of anymore.
